  • the solution was concentrated while being circulated in the cell suspension through the circulation circuit 30.
  • the liquid flow direction in the circulation circuit 30 was set to the direction of flowing from the circulation inlet port 17 of the storage container 3 to the cell suspension introduction port 18 of the cell suspension treatment device 6 (step (b)).
  • the pump 12 was stopped after the bubble sensor 10 detected the bubbles. Subsequently, the pump 13 and the pump 14 were driven to concentrate the cell suspension in the storage container 3, and after the pump 14 was driven for 70 seconds, the pump 13 and the pump 14 were stopped (step (c)).
  • the driving time of 70 seconds for the pump 14 was a time when it was expected that ideal concentration could be performed in consideration of the flow rates of the pumps 12, 13, and 14.
  • the clamp 21 is opened, the clamp 22 is closed, the flow rate is adjusted so that the pump 12 is 200 mL / min and the pump 13 is 450 mL / min, and the pump is driven for 120 seconds.
  • the cell suspension in the storage container 3 was diluted.
  • the flow rate was set so that the pump 13 was 450 mL / min and the pump 14 was 200 mL / min, and the cell suspension was filtered.
  • the pump 12 was driven for 120 seconds and then stopped.
  • the clamp 24 is opened, the clamp 23 is closed, the pump 13 is turned on at 100 mL / min, and the cell suspension is supplied from the circulation inlet port 17 of the storage container 3 to the cell suspension inlet 18 of the cell suspension processor 6.
  • the cell suspension in the cell suspension treatment device 6 and the circulation circuit 30 was collected from the collection path 31 to the collection container 5 (step (d)).
  • Comparative Example 2 performed by the same processing method, the cause is unknown, but since the amount of liquid filtered by the pump 14 was small as opposed to Comparative Example 1, before moving to the step of diluting with physiological saline. The amount of liquid in the storage container 3 increased, and the amount of unnecessary components in the cell concentrate could not be reduced to the target concentration.
